Patent EP-0761981-A3 (EP)
Inventor: HARADA HIDEOMI
IPC: F04D29/46
Filed: 1996-09-09
Abstract: An impeller-driven turbomachinery for use in centrifugal
and mixed flow pump overcomes operational difficulties, such as
flow separation and generation of surge at low flow rates,
and increases performance at flow rates above design flow rate. The
turbomachinery is provided with variable-angle inlet guide vane (6)
and variable-angle diffuser vanes (4), and the diffuser section is
constructed according to a fluid dynamic principle, where the setting
angle of the airbil shaped vaines equals the impeller exit angle,
increased with a certain attack angle. A convenient
operational parameter, chosen from such variables as input
current (S11) to drive motor, rotational speed (S13) or torque (S12) of the drive
motor (M), inlet/exit pressures (S14,S15), and fluid velocity, is monitored
during the operation by means of sensors strategically attached
to parts of the operating system. Real time changes in the
operating parameter is measured and the setting angle of the inlet
guide vane (6) is adjusted in accordance with a predetermined
relation between inlet flow volume rates and flow angle of the
fluid exiting from the impeller (2) so as to maintain the fluctuations
in the monitored operating parameter below a threshold value. If
the targeted head value is not produced under this adjustment,
the setting angle of the diffuser vanes (4) or the rotational
speed of the impeller (2) can be adjusted to operate
the system while avoiding surge and other problems encountered
at low flow rates. The proposed turbomachinery and method of
operations are highly cost-effective because the control
methodology is based on theoretical analysis of the flow pattern,
and it is not necessary to determine
the operating characteristics of each production lot of fluid
machines, thus saving the cost of software development for
different machines.

Abstract: A method and apparatus are disclosed that mitigate the induction of baseband
interference that can form time-division radios (e.g., radios that radiate an RF signal with a time-varying
power envelope). A radio (700) comprising an embodiment of the present invention
radiates, in transmit mode, an information-bearing signal. In some or all idle modes, the radio
(700) radiates at least one energy-reducing pulse (600), but in an idle-mode channel. These
energy-reducing pulses (600) reduce the energy in the fundamental frequency component of the
average RF power envelope of the radio and also reduce the energy in the harmonics of the
fundamental frequency.

Abstract: There is described a grip that is to be 
positioned on and adhered to the upper portion of a 
golf club shaft (30). The grip is defined by a strip (S) 
consisting of an open pored felt layer (40) having a 
generally flat inner surface and a smooth closed pore 
polyurethane layer (44) having its inner surface bonded to 
the outer surface of the felt layer (40). The pores (46) of the 
polyurethane layer (44) extend generally normal to the 
longitudinal axis of the strip (S) and the felt layer 
provides strength for the polyurethane layer while the 
polyurethane layer both absorbs shocks and provides 
tackiness so as to inhibit slippage of a user's hand 
relative to the shaft. The ratio of the thickness of 
the polyurethane layer to the felt layer has a minimum 
of about 0.18 and the strip is spirally wrappable 
about the shaft and adhered thereto.

Abstract: In the non-sintered nickel electrode for an
alkaline storage battery according to the invention, a
yttrium metal powder and/or a yttrium compound powder
has been added to a particulate active material comprising
composite particles each consisting of a nickel
hydroxide core and a sodium-doped cobalt compound

Abstract: An adaptive trellis decoder (40) seamlessly switches
between multiple operational modes. The decoder switches
between multiple modes and accommodates data type transitions
using a single state transition trellis with a predetermined
number of states. The system decodes trellis encoded video data
encoded in different formats respectively containing different
numbers of levels associated with different modes. The decoder
system adaptively operates in response to a configuration signal
distinguishing between the modes, and employs a state transition
trellis with the same number of trellis decoding states for
decoding encoded data of different formats. The state transition
decoding trellis may also be reset to a predetermined state in
response to a synchronization signal (10) generated as a result of
a transition from one type of data to another or in response to a
mode change.

Abstract: A less complex maximum likelihood detector can be
implemented in a partial response maximum likelihood (PRML)
system without degrading system performance by saturating y
values from a gain control loop to a smaller range before the
y values are supplied to the maximum likelihood detector. A
quantity "D" of a maximum likelihood detector operating in
accordance with a partial response scheme has a particular
relationship with respect to the maximum (ymax) of the y input
values processed by the maximum likelihood detector. In some
embodiments, y values from a gain control loop are saturated
from a first larger range (defined by ymaxreal) to a second
smaller range (defined by a value SAT) which is at least as
great as the ymax of the ideal input signal (ymaxideal) for
the partial response scheme. The saturated y values are
provided to the maximum likelihood detector. The D of the
maximum likelihood detector (given the partial response scheme
and the smaller range of y values) is in a different "two to
the power of an integer range" than the D would have been
given the same partial response scheme but the larger range of
y values.
